I can't visualise demux_viz.qzv file on QIIME view

Hi all, I'm new to QIIME2. However, I managed to import data demultiplexed paired end sequences and I created a manifest file, following QIIME docs and QIIME2 forum assistance. Here are my previous codes:

qiime tools import --input-path /Users/shandrytebele/Desktop/16sRNA/manifest.txt --type 'SampleData[PairedEndSequencesWithQuality]' --output-path /users/shandrytebele/Desktop/16sRNA/paired_end_demux.qza --input-format PairedEndFastqManifestPhred33V2

qiime demux summarize --i-data ./paired_end_demux.qza --o-visualization ./demux_seq_summary_viz.qzv

Now, I can't view this file on QIIME view and I get a pop out message saying the page is not found under visualisation, under details it shows my file name and provenance data shows : * uuid:"3490cd7a-ee53-4737-bee9-888eb70125cd"

  • type:"SampleData[PairedEndSequencesWithQuality]"
  • format:"SingleLanePerSamplePairedEndFastqDirFmt"

Here is the screenshot of my files:

Kindly assist colleagues.

Thank you in advance

Hello @Shandry123,

Welcome to the forums! :qiime2:

Can you also post a screenshot of that pop-up message you get when you drag and drop your .qzv file into view.qiime2.org? Your fastq files look ok, and I would like to learn more about the .qzv error.

Would you be willing to post your demux_seq_summary_viz.qzv file so we can check to see if it works on our machines? If this data is private, you are in no way obligated to share!

Do you think there is something wrong with my PC or QIIME2 view system might be down?

I meant " Can't view..."

Hi @Shandry123 - two things

  1. Can you try again with a different browser? Firefox or chrome.
  2. Please DM me a link to the file you are trying to load
